Description

La présente invention se rapporte à une installation permettant de transporter horizontalement un bateau sur un sol ferme, à sec. Une telle installation est intégrée dans une installation plus complexe permettant de transporter un bateau de l'eau jusqu'à un sol ferme et vice-versa.The present invention relates to an installation for horizontally transporting a boat on firm, dry ground. Such an installation is integrated into a more complex installation making it possible to transport a boat from water to firm ground and vice versa.

Certaines installations de mise à sec ou à l'eau de navires comprennent un élévateur destiné à hisser chaque navire de l'eau jusqu'au niveau du sol. Un tel élévateur comprend une plateforme soulevée par des treuils. Le bateau repose sur la plateforme pendant le transport de l'eau jusqu'au niveau du sol, c'est à dire jusqu'à la position où il émerge. Il faut ensuite déplacer horizontalement chaque bateau depuis l'élévateur jusqu'à une position de garage.Some ship dry or water installations include a lift to lift each ship from the water to ground level. Such an elevator includes a platform raised by winches. The boat rests on the platform during the transport of the water up to ground level, that is to say to the position where it emerges. Each boat must then be moved horizontally from the elevator to a garage position.

Le transport horizontal d'un navire s'effectue généralement au moyen de chariots à roues placés sous la quille de ce navire. Ce mode de transport manque de souplesse pour absorber les irrégularités du terrain et pour répartir la charge du navire. Par ailleurs ces chariots ne desservent qu'une seule direction ce qui limite le nombre de bateaux pouvant être garés sur une surface donnée.The horizontal transport of a ship is generally carried out by wheeled carts placed under the keel of this ship. This mode of transport lacks flexibility to absorb the irregularities of the ground and to distribute the load of the ship. Furthermore, these trolleys only serve one direction, which limits the number of boats that can be parked on a given surface.

Le brevet anglais 1 016 785 décrit une installation de transport à chariots permettant de déplacer le bateau suivant une direction horizontale quelconque. Le bateau repose sur une file de poutres disposées perpendiculairement à son axe longitudinal. Chaque poutre repose à ses extrémités sur deux chariots. Les différents chariots sont rangés sur deux files et chaque tranche du bateau est supportée, par l'intermédiaire de la poutre et des chariots, ce qui assure une bonne répartition des charges. L'appui de chaque poutre sur chaque chariot s'effectue par l'intermédiaire d'un vérin hydraulique à double effet. Les vérins permettent, lorsque les poutres sont appuyées sur le sol, de soulever les chariots au-dessus des rails et ainsi de les faire pivoter d'une voie à une autre voie. Des changements de direction peuvent donc être réalisés. Les vérins permettent sourtout de supporter élastiquement et isostatiquement le bateau par rapport au sol. Les vérins supportant les poutres sont répartis en trois groupes. Tous les vérins d'un même groupe sont connectés entre eux de manière que les réactions de ces vérins soient égales. Un premier groupe comprend les vérins associés à une fraction des chariots alignés sur l'une des voies. Le second groupe comprend les vérins associés à une fraction des chariots alignés sur l'autre voie. Le troisième groupe regroupe l'ensemble des vérins montés sur les chariots de support à un groupe de poutres support situées à l'extrémité de la file de poutres. Chaque groupe de vérins équivaut à un supportage fictif au centre de la figure géométrique qu'ils définissent. Les trois résultantes dues aux trois groupes de vérins sont localisées aux sommets d'un triangle isocèle dont la hauteur principale est parallèle à l'axe longitudinal du bateau. Le bateau ne repose que sur deux files de tins parallèles pour que les efforts sur ces tins soient équilibrés.British patent 1,016,785 describes a trolley transport installation making it possible to move the boat in any horizontal direction. The boat rests on a line of beams arranged perpendicular to its longitudinal axis. Each beam rests at its ends on two carriages. The different carriages are stored in two rows and each section of the boat is supported, via the beam and the carriages, which ensures good load distribution. The support of each beam on each carriage is effected by means of a double-acting hydraulic cylinder. The jacks allow, when the beams are supported on the ground, to lift the carriages above the rails and thus to rotate them from one track to another track. Changes of direction can therefore be made. The cylinders allow above all to support elastically and isostatically the boat with respect to the ground. The cylinders supporting the beams are divided into three groups. All the cylinders in the same group are connected together so that the reactions of these cylinders are equal. A first group comprises the jacks associated with a fraction of the carriages aligned on one of the tracks. The second group includes the cylinders associated with a fraction of the carriages aligned on the other track. The third group includes all of the jacks mounted on the support carriages to a group of support beams located at the end of the row of beams. Each group of cylinders is equivalent to a fictitious support at the center of the geometric figure that they define. The three resulting from the three groups of cylinders are located at the vertices of an isosceles triangle whose main height is parallel to the longitudinal axis of the boat. The boat only rests on two rows of parallel tins so that the forces on these tins are balanced.

On a cherché à réaliser un supportage en trois points sur une poutre, dans le brevet francais 2170.440 le bateau est supporté sur la poutre au milieu et latéralement par deux tins latéraux d'accorage s'appuyant aux extrémités de cette poutre. Les tins lateraux d'accorages appuient sur la poutre par l'intermédiaire de vérins qui permettent le règlage en hauteur en fonction du bateau supporté. L'équilibrage des efforts entre les différents tins est malgré tout imparfait. L'accorage doit être réalisé par tâtonnements et nécessite des interventions manuelles. Outre cet inconvénient concernant l'accorage, ces installations connues ne permettent pas de supporter des navires de forts tonnages et de grandes largeurs.We sought to achieve support at three points on a beam, in French patent 2170.440 the boat is supported on the beam in the middle and laterally by two lateral anchoring tins bearing on the ends of this beam. The lateral anchoring ends press on the beam by means of jacks which allow the height adjustment according to the supported boat. The balancing of efforts between the different ends is, however, imperfect. The docking must be done by trial and error and requires manual intervention. In addition to this drawback concerning docking, these known installations do not allow vessels of large tonnages and large widths to be supported.

Le brevet anglais 1 229 261 décrit une installation de transport dans laquelle le bateau est supporté par deux files de poutres-supports montées sur des trains roulants. Le bateau s'appuie sur chaque poutre-support par un seul appui et il est ainsi supporté par deux files parallèles d'appuis. Il n'est pas possible de prévoir un nombre plus élevé de poutres et d'appuis si l'on veut que les réactions des appuis soient équilibrées.British patent 1 229 261 describes a transport installation in which the boat is supported by two rows of support beams mounted on running gear. The boat is supported on each support beam by a single support and is thus supported by two parallel rows of supports. It is not possible to provide a higher number of beams and supports if we want the reactions of the supports to be balanced.

La présente invention a pour objet une installation destinée à assurer le transport d'un navire de fort tonnage en le supportant, isostatiquement, par au moins trois files de tins paralleles du à l'axe longitudinal du navire.The subject of the present invention is an installation intended to transport a large tonnage ship by supporting it, isostatically, by at least three rows of tins parallel to the longitudinal axis of the ship.

Equilibrage des efforts sur les différents tins situés sous une tranche est assure. Les tins latéraux assurant la stabilité du navire, à la mise à l'eau ou à la sortie de l'eau ou pendant les déplacements, sont maintenus en contact permanent contre la coque du navire. L'accorage ou l'attinage est réalisé automatiquement.Balancing of the forces on the different tins located under a section is ensured. The lateral tins ensuring the stability of the vessel, when launching or leaving the water or during movement, are kept in permanent contact against the hull of the vessel. The coupling or the hitching is carried out automatically.

Conformément à l'invention, cette installation, telle que définie dans le préambule de la revendication se caractérise par le fait que les poutres-support sont disposées selon au moins trois files parallèles à l'axe longitudinal du bateau et décalées les unes des autres de manière qu'une file dite latérale soit plus éloignée qu'une file dite centrale par rapport au dit axe longitudinal et que chacun des deux groupes de vérins procurant une résultante décalée de l'axe longitudinal du bateau connecte des vérins des chariots de poutres-support d'une dite file latérale et des vérins de chariots de poutres-support de ladite file centrale disposés sur le même côté de l'axe longitudinal du bateau, le groupe de vérins dont la résultante est sur l'axe longitudinal du bateau connectant d'autres vérins de chariots de poutres-support d'au moins une des dites files.According to the invention, this installation, as defined in the preamble of the claim, is characterized in that the support beams are arranged in at least three rows parallel to the longitudinal axis of the boat and offset from each other by so that a so-called lateral queue is more distant than a so-called central queue with respect to said longitudinal axis and that each of the two groups of jacks providing a result offset from the longitudinal axis of the boat connects jacks of support beam carriages a said lateral file and cylinders of support beam carriages of said central file arranged on the same side of the longitudinal axis of the boat, the group of cylinders whose resultant is on the longitudinal axis of the boat connecting other cylinders of support beam carriages of at least one of said lines.

Selon une autre caractéristique, elle comporte au moins une poutre de la file centrale dont un des vérins est connecté à des vérins de support des poutres-support d'une file latérale, l'autre vérin de ladite poutre étant connecté à des vérins de support des poutres-support de l'autre file latérale.According to another characteristic, it comprises at least one beam of the central file of which one of the jacks is connected to support jacks of the support beams of a lateral file, the other jack of said beam being connected to support jacks support beams on the other side row.

Selon encore une autre caracteristique, l'une au moins des poutres-support centrales est réunie à ses extrémités par deux articulations à deux poutres-support latérales, l'extrémité accouplée de chaque poutre latérale avec la poutre centrale s'appuyant sur un chariot.According to yet another characteristic, at least one of the central support beams is joined at its ends by two articulations with two lateral support beams, the coupled end of each lateral beam with the central beam resting on a carriage.

Dans l'installation de la figure 4, les chariots 43 et 51 roulent respectivement sur des voies latérales 65 et 66.The carriages associated with the beams 3 of the central file roll on the central tracks 62 and 63. At least two lateral tracks are arranged in parallel and on either side of the central tracks. The carriages 41 run on an outer lateral track 61, the carriages 53 run on an outer lateral track 64. Each of the tracks comprises two rails. In the installation shown in FIGS. 1 and 2, the carriages 43 and 51 roll respectively on the central tracks 62 and 63. In the installation of FIG. 4, the carriages 43 and 51 roll respectively on lateral tracks 65 and 66 .

Les poutres-support sont disposées de manière à former trois files de poutres décalées transversalement (perpendiculairement à l'axe 13) du fait que les poutres 4 et 5 des files latérales sont associées à des chariots roulant sur des voies écartées des voies sur lesquelles roulent les chariots associés aux poutres 3 de la file centrale. Les milieux des poutres 3, c'est à dire les points situés chacun à égales distances des points d'appui d'une poutre sur les chariots, sont alignés sur une ligne fictive située entre une ligne fictive passant par des milieux des poutres 4 d'une file latérale et une ligne fictive passant par les milieux des poutres 5 de l'autre file latérale. Les extrémités des poutres centrales et des poutres latérales sont écartées, perpendiculairement à l'axe 13, les unes par rapport aux autres.The support beams are arranged so as to form three rows of beams offset transversely (perpendicular to the axis 13) due to the fact that the beams 4 and 5 of the lateral rows are associated with carriages traveling on tracks separated from the tracks on which run the carriages associated with the beams 3 of the central file. The midpoints of the beams 3, that is to say the points each located at equal distances from the support points of a beam on the carriages, are aligned on a fictitious line situated between a fictitious line passing through the midpoints of the beams 4 d 'a lateral file and a fictitious line passing through the midpoints of the beams 5 of the other lateral file. The ends of the central beams and the lateral beams are spaced, perpendicular to the axis 13, with respect to each other.

Chaque chariot comprend quatre roues roulant par paires sur les deux rails. Ainsi le chariot 31 comprend quatre roues 311, 312, 313, 314 qui sont guidées dans des paliers du châssis de bogie 313. De préférence les poutres-support sont perpendiculaires aux rails mais elles peuvent aussi être parallèles aux rails à la suite d'un changement de direction effectué par pivotement des chariots.Each carriage comprises four wheels rolling in pairs on the two rails. Thus the carriage 31 comprises four wheels 311, 312, 313, 314 which are guided in bearings of the bogie frame 313. Preferably the support beams are perpendicular to the rails but they can also be parallel to the rails following a change of direction by pivoting the carriages.

Chaque chariot comporte un vérin hydraulique. Chaque poutre-support s'appuie à ses extrémités sur deux vérins montés sur chariots. Ainsi chaque poutre 3 s'appuie sur les vérins 32 et 34 montés respectivement sur les chariots 31 et 33. Chaque poutre 4 s'appuie sur les vérins 42 et 44 montés respectivement sur les chariots 41 et 43. Chaque poutre 5 s'appuie sur les vérins 52 et 54 montés respectivement sur les chariots 51 et 53.Each carriage has a hydraulic cylinder. Each support beam is supported at its ends on two jacks mounted on carriages. Thus each beam 3 is supported on the jacks 32 and 34 mounted respectively on the carriages 31 and 33. Each beam 4 is supported on the jacks 42 and 44 mounted respectively on the carriages 41 and 43. Each beam 5 is supported on the jacks 52 and 54 mounted respectively on the carriages 51 and 53.

Les vérins 32 et 34, 42 et 44, 52 et 54 forment trois groupes. Dans chaque groupe, les chambres inférieures des vérins sont interconnectées. La pression hydrostatique' étant la même en tout point du circuit hydraulique de chaque groupe, tous les efforts développés par les vérins de ce groupe sont égaux. Ainsi sur les figures 6 à 8, les traits interrompus, référencés I, II, III, délimitent les vérins appartenant aux trois groupes. Chaque groupe de vérins équivaut statiquement à un supportage ponctuel fictif dont la résultante, repérée R1, R2, ou R3, est égale à la somme des réactions -égales- des vérins de ce groupe. Les résultantes des trois groupes de vérins sont localisées aux sommets d'un triangle isocèle dont la hauteur principale est parallèle à l'axe longitudinal 13 du bateau. Les deux groupes 1 et Il donnent deux résultantes qui sont symétriques et décalées par rapport à l'axe longitudinal 13 du bateau. Le troisième groupe III donne une résultante passant approximativement par l'axe 13 du bateau. On peut tendre à égaliser les charges sur tous les vérins c'est à dire entre les vérins appartenant à des groupes différents. A cet effet le centre de gravité du navire doit se situer au barycentre des trois points fictifs de supportage, pondérés du nombre de vérins constituant chacun de ces points.The cylinders 32 and 34, 42 and 44, 52 and 54 form three groups. In each group, the lower chambers of the cylinders are interconnected. Hydrostatic pressure ' being the same at every point of the hydraulic circuit of each group, all the forces developed by the cylinders of this group are equal. Thus in Figures 6 to 8, the broken lines, referenced I, II, III, delimit the cylinders belonging to the three groups. Each group of jacks is statically equivalent to a fictitious punctual support, the result of which, marked R1, R2, or R3, is equal to the sum of the - equal - reactions of the jacks in this group. The results of the three groups of jacks are located at the vertices of an isosceles triangle whose main height is parallel to the longitudinal axis 13 of the boat. The two groups 1 and II give two results which are symmetrical and offset with respect to the longitudinal axis 13 of the boat. The third group III gives a result passing approximately by the axis 13 of the boat. We can tend to equalize the loads on all the cylinders, that is to say between the cylinders belonging to different groups. For this purpose the center of gravity of the ship must be located at the barycenter of the three fictitious support points, weighted by the number of cylinders constituting each of these points.

Chacun des groups de vérins dont la résultante est décalée comprend des vérins supportant des poutres-support centrales et des vérins supportant des poutres latérales. Ainsi, dans le groupe I, des vérins supportant des poutres centrales 3 sont connectés à des vérins supportant des poutres latérales 4. Dans le groupe II, des vérins supportant des poutres centrales 3 sont connectés à des vérins supportant des poutres latérales 5. Certaines poutres centrales reposent sur un vérin connecté aux autres vérin de l'un des groupes I ou II, l'autre vérin associé à chacune de ces poutres étant connecté aux vérins de l'autre groupe. Les deux vérins de support de certaines poutres centrales font partie du groupe III dont la résultante est sur l'axe du bateau. Les deux vérins de support de chaque poutre latérale font partie généralement d'un même groupe. Ainsi le poids du bateau est transmis par les tins 21 sur les poutres-support 3 et les vérins 32 et 34 sont soumis à des efforts. Si les tins d'accorage 22 n'étaient pas appliqués contre la coque du bateau, l'interconnexion des vérins du groupe I tendrait à faire sortir les pistons des vérins 42 et 44. De même si les tins d'accorage 23 n'étaient pas appliqués contre la coque, l'interconnexion des vérins du groupe Il tendrait à faire sortir les pistons des vérins 52 et 54.Each of the groups of cylinders whose result is offset comprises cylinders supporting central support beams and cylinders supporting lateral beams. Thus, in group I, jacks supporting central beams 3 are connected to jacks supporting lateral beams 4. In group II, jacks supporting central beams 3 are connected to jacks supporting lateral beams 5. Certain beams central units rest on a jack connected to the other jack of one of the groups I or II, the other jack associated with each of these beams being connected to the jacks of the other group. The two support cylinders of certain central beams are part of group III, the result of which is on the axis of the boat. The two support cylinders of each lateral beam are generally part of the same group. Thus the weight of the boat is transmitted by the tins 21 on the support beams 3 and the jacks 32 and 34 are subjected to forces. If the docking blocks 22 were not applied against the hull of the boat, the interconnection of the cylinders of group I would tend to cause the pistons of the cylinders 42 and 44 to come out. Likewise if the docking blocks 23 were not not applied against the hull, the interconnection of the group's cylinders It would tend to cause the pistons of the cylinders 52 and 54 to come out.

Les figures 6 à 8 représentent diverses dispositions des poutres-support.Figures 6 to 8 show various arrangements of the support beams.

L'installation représentée sur la figure 6 comporte un nombre plus élevé de poutres-support centrales que de poutres-support latérales. Elle convient à un bateau à quille centrale.The installation shown in Figure 6 has a higher number of central support beams than lateral support beams. It is suitable for a center keel boat.

L'installation représentée sur la figure 7 comprend des poutres centrales et des poutres latérales plus nombreuses que dans la disposition de figure 6.The installation shown in FIG. 7 comprises more central beams and lateral beams than in the arrangement in FIG. 6.

L'installation représentée sur la figure 8 comporte, dans le groupe III, des vérins supportant des poutres centrales 3 et des poutres latérales 4 et 5.The installation shown in FIG. 8 comprises, in group III, jacks supporting central beams 3 and lateral beams 4 and 5.

Les installations des figures 6, 7 et 8 assurent l'accorage automatique entre des tins centraux et des tins latéraux. La figure 3 montre une variante dans laquelle les poutres-support latérales 4 et 5 sont équipées respectivement de vérins 45 et 55 servant à déplacer verticalement les tins d'accorage 22 et 23 lorsque la coque du bateau est courbe. L'équilibrage des efforts entre les différents vérins s'effectue comme précédemment et l'accorage est encore réalisé automatiquement.The installations of FIGS. 6, 7 and 8 ensure automatic docking between central tins and lateral tins. FIG. 3 shows a variant in which the lateral support beams 4 and 5 are equipped with jacks 45 and 55 respectively, serving to vertically move the docking tins 22 and 23 when the hull of the boat is curved. The balancing of the forces between the different cylinders is carried out as previously and the docking is still carried out automatically.

La figure 5 représente une poutre-support continue pouvant être utilisée dans l'installation. Cette poutre continue comporte plusieurs poutres-support perpendiculaires à l'axe longitudinal du bateau. Chaque poutre est articulée à la poutre adjacente. La poutre latérale 4 est réunie à la poutre centrale 3 par l'articulation 71. La poutre latérale 5 est réunie à la poutre centrale 3 par l'articulation 72. L'extrémité extérieure de la poutre latérale 4 s'appuie, par l'intermédiaire d'un vérin, sur un chariot 41 à quatre roues roulant sur la voie 61. L'extrémité extérieure de la poutre 5 s'appuie, par l'intermédiaire d'un vérin, sur un chariot 53 à quatre roues roulant sur la voie 64. Les extrémités accouplées des poutres 4 et 3 s'appuient, par l'intermédiaire d'un vérin, sur un chariot 31 à quatre roues roulant sur la voie 62. Les extrémités accouplées des poutres 3 et 5 s'appuient, par l'intermédiaire d'un vérin, sur un chariot 33 à quatre roues sur la voie 63.Figure 5 shows a continuous support beam that can be used in the installation. This continuous beam has several support beams perpendicular to the longitudinal axis of the boat. Each beam is articulated to the adjacent beam. The lateral beam 4 is joined to the central beam 3 by the articulation 71. The lateral beam 5 is joined to the central beam 3 by the articulation 72. The outer end of the lateral beam 4 is supported, by the intermediate of a jack, on a carriage 41 with four wheels rolling on the track 61. The outer end of the beam 5 is supported, by means of a jack, on a carriage 53 with four wheels rolling on the track 64. The coupled ends of beams 4 and 3 are supported, by means of a jack, on a carriage 31 with four wheels rolling on track 62. The coupled ends of beams 3 and 5 are supported, by via a jack, on a four-wheeled carriage 33 on track 63.

L'installation est équipée, en totalité ou en partie, de chariots automoteurs 31, 33, 41, 43, 51, 53. Chaque chariot automoteur, tel que le chariot 31, a au moins quatre roues indépendantes. Chaque axe de roue est indépendant de l'axe de la roue coaxiale. Les axes des roues sont guidés dans des boites d'essieu fixées au châssis de bogie tel que 315. Deux des quatre roues sont motrices. Chacune de ces roues motrices est accouplée à un moteur hydraulique. Ainsi la roue motrice 311 est accouplée au moteur 316, la roue motrice 314 étant accouplée au moteur 317. Chaque chariot a une roue motrice sur chaque rail. Les deux roues motrices sont symétriques par rapport à l'axe du vérin ce qui permet de loger facilement les moteurs.The installation is equipped, in whole or in part, with self-propelled carriages 31, 33, 41, 43, 51, 53. Each self-propelled trolley, such as the trolley 31, has at least four independent wheels. Each wheel axis is independent of the axis of the coaxial wheel. The wheel axles are guided in axle boxes fixed to the bogie chassis such as 315. Two of the four wheels are driven. Each of these drive wheels is coupled to a hydraulic motor. Thus the driving wheel 311 is coupled to the motor 316, the driving wheel 314 being coupled to the motor 317. Each carriage has a driving wheel on each rail. The two drive wheels are symmetrical with respect to the axis of the jack, which makes it easy to house the motors.

Il est bien entendu que l'on peut, sans sortir du cadre de l'invention, imaginer des variantes et perfectionnements de détails et de même envisager l'emploide moyens équivalents.It is understood that one can, without departing from the scope of the invention, imagine variants and improvements of details and even consider the use equivalent means.

Les chariots, au lieu de rouler sur des rails, pourraient rouler sur des voies non ferroviaires.The carts, instead of rolling on rails, could roll on non-railway tracks.
